middle; hind tibiae with the basal hall'wliite, 

 tlie tei-minal half blacli. Tarsi with tlie first 

 joint yellowish-white, the others brown. 

 First segment of abdomen sparsely but dis- 

 tinctly punctured, and with a narrow white 

 hair band on hind margin at sides. 



//a*.— Colorado (C. F. Baker, No. 1411) 

 on Elk River, 10 miles north of Steamboat 

 Springs, July i6, 1894. 



Resembles a species from Florida of which 

 I have only the $ , but that differs at once 

 by the smooth first segment of abdomen, 

 hnmaculate tegblae, dark middle tibiae, etc. 



Differs from tnodesta by the white face, 

 the narrower and more pointed supraclypeal 

 pale area, the darker wings, etc. ; from ajfiiiis 

 at once by the shape of the face-marks, spot 

 on tegulae, etc. ; from rugosula by the 

 greater size, darker wings, and pointed supra- 

 clypeal area; from coloradensis by the darker 

 wings, narrower lateral face-marks, etc. 



Prosapis coloradensis, n sp. — $ about 

 J.J mm. long, stoutly built, head and thorax 

 closely punctured, scutellum as closely as 

 mesothorax, black with cream-colored mark- 

 ings. Head large, rather long, face moder- 

 ately narrowed below, vertex confluentiv 

 punctured, antennae all dark, flagellum 

 brown, scape broad, dilated, with a conspic- 

 uous terminal hump on outer side. Face 

 below antennae cream-color, supraclypeal 

 projection short and truncate, lateral upward 

 extensions of pale color very broad, slightly 

 excavated inwardly at base by antennal 

 sockets, terminating in a broad oblique trun- 

 cation, a little higher up than the middle of 

 the scape. 



Hind border of prothorax with two very 

 narrow yellow lines ; tubercles with the usual 

 pale yellow patch, convex and shining, with- 

 out a dark spot. Tegulae with a light spot. 

 Pleura closelj' punctured. Enclosed area of 

 metathorax rugose, without the large shining 

 pits of some species. Pubescence of dor- 

 sulum gray. Wings hyaline. Femora black ; 

 tibiae black, anterior tibiae white in front, 

 middle tibiae with the basal and apical fifths 



white, hind tibiae with the basal two-fifths 

 white and a white dot at tip. Tarsi brown, 

 first joint and spot on second joint of four 

 hind tarsi white. First segment of ab- 

 domen minutely but distinctly and rather 

 closely punctured, with no lateral hair band. 



Hab. — Colorado ; Chamber's Lake, Lari- 

 mer Co., July 18, 1895, 9500 feet (C. F. 

 Baker). 



Prosapis digitatus, n. sp — J about 44 

 mm. long, black with very pale yellow mark- 

 ings, head and thorax closely punctured. 

 Head of ordinary size, face moderately nar- 

 rowed below, antennae dark brown, scape 

 not dilated. Face below antennae very pale 

 yellow, the yellow extending upwards in the 

 median line as a rather narrow, conical, 

 truncate projection; at the sides it extends 

 in the form of narrow, straight, finger-like 

 projections, pointing somewhat inwards, 

 well away from the orbital margin. Pro- 

 thorax, including the tubercles, wholly dark. 

 Tegulae without a light spot. Punctuation 

 of mesothorax hardly so close as in some 

 species, that of scutellum slightly more 

 sparse. Pleura with close, shallow punctures. 

 Base of metathorax more or less radiatelv 

 wrinkled. Wings smoky. Femora black, 

 except a light spot at the extreme tip of the 

 first four. Tibiae black, anterior tibiae yel- 

 lowish in front, middle of extreme base, and 

 hind tibiae for basal two-fifths. Tarsi brown- 

 ish, more or less yellow basally. First ab- 

 dominal segment shining, with very sparse, 

 small punctures. Pubescence of abdomen 

 very sparse. 



Hnb. — Colorado; Steamboat Springs, 

 July 13, 1894 (C. F. Baker, No. 1329). 



Easily known by the dark tubercles, and 

 lateral face-marks, which free from the orbital 

 margin, are straight and not enlarged at 

 their ends.
